Mitigation checklist

Recommended fix / mitigation

do not expose rclone serve restic to untrusted clients; bind it to trusted networks only, and avoid publishing a backend subdirectory when the backend credential can also access parent or sibling objects. Prefer serving the exact backend root you intend to expose.
